Outcome

A recombinant inbred line (RIL) population developed from a cross between Alfetta (Pisum sativum) and P651 (P. fulvum) was evaluated for disease resistance and was genotyped using 1536 Single Nucleotide Polymorphisms (SNP) Illumina Golden Gate array. A high density genetic linkage map consisting of 733 SNP markers covering a genetic distance of 682.1 cM was used for quantitative trait loci (QTL) analysis. Six QTLs were identified for mycosphaerella blight under field and 3 additional QTLs were identified under greenhouse conditions. HIFs evaluated under field conditions in 2015 at Saskatoon showed a wide range of variation in disease scores and other traits. Genotyping of HIFs was conducted using 8 markers designed from an Illumina GoldenGate array.
